能帮我吗?

我正在尝试配置ECS群集以使用EFS共享文件,但是我面临以下问题:

如果仅在ECS任务中声明一个卷,则容器正常启动,但是如果我尝试将外部卷与容器文件夹映射,则会发生此问题。

我遵循了本教程:https://docs.aws.amazon.com/AmazonECS/latest/developerguide/using_efs.html,看来问题不在安全组中,而是容器本身。

我正在使用Redmine的高山版本。

遵循配置摘要:


  ...
  "mountPoints": [
        {
          "readOnly": null,
          "containerPath": "/usr/src/redmine/files",
          "sourceVolume": "attachments"
        }
      ],

  ...

  "volumes": [
    {
      "efsVolumeConfiguration": {
        "fileSystemId": "fs-xxxxx",
        "rootDirectory": "/mnt/efs/redmine"
      },
      "name": "attachments",
      "host": null,
      "dockerVolumeConfiguration": null
    }
  ],

谢谢。

日志显示:“没有这样的文件或目录”:使用前请确保efs上的目录存在。

其他注意事项: 您不能将“ efsVolumeConfiguration”与ECS-Fargate一起使用。当前仅适用于ECS-on-EC2(正在提供Fargate支持)。

我点击了那些链接以解决我的问题。我认为EFS还不能在ECS中使用。

我必须在EC2内映射EFS,然后才能从docker容器进行访问。
